Important to note that the induced mass (mass required by a given engine design that is not the engine itself) of Raptor 3, while far better than Raptor 2, still has a lot of room for improvement.

Thrust will exceed 300 tons with Raptor 3.x (thrust/mass>200), enabling 10,000 tons of thrust at liftoff and there might be up to 5 sec of Isp gain over time.

Getting close to the limit of known physics.

In a few years, we will finally have a Raptor 3/4 vacuum version (giant nozzle) that has an Isp of 380

That is one slick looking rocket engine.

It's so slick and clean looking ! It looks like the concept version of the engine.
